REENFOBCED TAB Application filed June 30,

My invention relates to reenforced guide tabs for guides, folders, indexes and the like, its primary object being the provision of a novel reinforcement of great simplicity.

Another of my objects is the provision of a reinforcement for guides and the like in which the reinforcement is "adapted to be formed or modified into any one of numerous shapes.

Another of my objects is the provision of a reinforcement for guides or the like which permits the use of a sliding tab made of celluloid or metal or similar material.

It is also my object to provide a reinforcement which will be not only superior to the prior reinforcements but which will be so simple in construction that-the material and labor cost of producing the reenforced guide tabs will be very much lower than with any of the prior devices of this character.

Having in view these objects and others which will be pointed out in the following description, I will now refer to the drawings, in which Figure .1 is a View in perspectlve of a guide with my reinforcement applied thereto.

Figure 2 is a View in perspective of a portion of a folder in which the tab permits the use of a slide, the tab being reenforced as in Figure 1.

Figure 3 is an edge view of the guide shown in Figure 1.

Figures 4 to 7 inclusive are edge views showing four of the numerous ways in which the tab may be bent from the forms shown in Figures 1 and 3.

Figure 8 is a sectional view showing a modification in which the reinforcement is partly folded upon itself.

In Figure l the numeral 10 designates a guide or the like. The top edge of this guide is folded over in the form of a flap 12 with a reenforcing material 13 between the parts 10 and 12. The end portions are cut away as shown-in Figure 1 so as to provide a tab for receiving writing either directly or through the application of a gummed label.

The reenforcing material 13 is preferably sheet steel which is very thin. It may,- how- 1980. Serial No. 464,850.

ever, be made of any other suitable sheet metal or celluloid or any other material which is sufficiently stiff and in sheet form. The reenforcing may extendjentirely across the guide as shown in Figure 1 or it may extend across only a portion ofthe width of the guide as shown in Figure 2. In applying the reenforcing to the guide, a suitable adhesive is employed to unite the parts 10 and 12 to each other and to the reenforcing 13. By employing pressure for uniting these parts the guide is produced without any material increase in thickness.

Figure 1 shows the use of the reinforcement on a guide. The same or a similar reinforcement may be used on folders as shown in Figure 2 or on indexes, file guides, cards, loose leaf indexes or bound book indexes. When made as shown in Figure 1, the forward surface of the tab is a writing surface, or a gummed label may be applied'to that surface with the writing appearing on the label. If desired, the tab may be produced with a window 14 in the folded portion 12 or in both the folded portion 12 and in the reinforcement, the window exposing the writing on the celluloid or other slide 15 which is inserted in a pocket provided by omitting the adhesive between one side or the other of the reinforcement and the corresponding part of the folded guide. Still another modification is shown in Figure 8 in which the reinforcement 13" is folded upon itself and provided with a window 14", the parts of the reinforcement being so spaced as to slidably receive a slide similar to the slide 15. The slide 15 may be made of any suitable writing material of which celluloid is only one example. When celluloid is used as a writing material, it must have at least one matte surface. Transparent celluloid may also be used as a cover for the window opening and numerous other transparent materials in strip form may be used for this purpose as well.

The reenforced guide tabs as above described may be used not only for numerous purposes but they may be also modified in variousways of which four are shown in Figures 4 to 7 inclusive. In Figure 4 the tab is bent into wedge-shape from its position as 130 shown in Figure 3. Thisleaves. an inclined writing surface which extends downwardly and forwardly. This form may also be rorided with a window similar to that of igure 2 or of Figure 8., Figure 5 shows the Figure 3 form with the tab bent downwardl y and forwardly while Figure 6 shows the same tab bent rearwardly and upwardly to expose a writin surface at substantially the I same angle. Figure 7 shows the tab of F igure 3 after it has been curled to expose a rounded writing surface. These four forms, however, are merely suggestive of the numerous forms into which the tabs of Figures 1 and 2 may be shaped.

Having thus described my invention in such full, clear and exact terms that its construction and operation will be readily understood by others skilled in the art to which it pertains, what I claim as new and desire to secure by Letters Patent of the United States is:

1. An index or the like having a tab at an edge thereof, said tab including a reinforcement of a relatively stiff but bendable material seated within a fold of the material of said index whereby said tab may be readily formed into any desired shape.

2. An index or the like having a tab at an edge thereof, said tab including a reinforcement of a relatively thin, flat, sheet of relatively stiff material seated within a fold of the material of said index, said reinforcement being secured to the back of said index, said folded over portion being provided with a window and being secured at its bottom and one lateral edge to said reinforcement to thus provide one open lateral edge for the insertion of a strip of writing material in the rear of the window in said folded over portion.

3. An index or the like having a tab at an edge thereof, said tab including a reinforce ment of a relatively stiff but bendable material seated within a fold of the material of said index whereby said tab may be readily formed into any desired shape, said reinforcement being secured to both said igdex V V and said folded over portion thereoff 4. An index or the like having a tab at an edge thereof, said tab including a reinforcement of a relatively thin, flat, sheet of relatively stiff material seated within a fold of the material of said index, said index being provided with a pocket underneath said'folded-over portion for slidably receiving a strip of writing material, and said folded-over portion being provided with a window for-r. V

ward of the pocket.

In testimony whereof I aflix my signature.
